TEA 0R COFFEE FILTER.

SPECIFICATION forming part of Letters Application filed March 5, 1892.

To all whom it may concern,.-

Be it known that I, EMMET R. AUSTIN, a citizen of the United States,residing at Norwalk, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in Tea orCoffee Filters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to provide a and easily-attached filterfor use in making tea or coee, it being desirable in a device of thisclass that it be so constructed that it may be readily applied to anyordinary tea or coffee pot, that it may be readily removed and cleaned,and that the bag be prevented from swinging forward in pouring andclosing up the base of the spout.

With these ends in view I have devised the simple and novel iilter whichI will now describe, referring by numbers to the accompanying drawings,forming part of this specification, in which- Figure l is an elevationof a coffee-pot, the side being broken away to show the applicationthereto of my novel filter; Fig. 2, a section of the bag, showing themetallic parts by which it is applied and held in place; Fig. 3, a planview of the filter complete, and Fig. 4 a view of the holder removed.

l denotes the bag, which is provided at its upper end with a ring 2,provided with three (more or less) upwardly and inwardly turned lugs 3.In practice the ring and lugs are all formed from a single piece ofwire, as indicated in Fig. 2. The holder consists of a strip of metal(wire may be used, if preferred) comprising a loop 4, which is adaptedto hang over the edge of a tea or coffee pot, as indicated in Fig. l, ahand-piece 5 for convenience in manipulation, a downwardly-extendingloop 6, which extends into the bag and which holds the latter inposition, so that it cannot swing forward against the base of the spoutand interfere with the free passage of the liquid in pouring, and a ring7, which is adapted to pass within ring 2 and to be locked in positionby lugs 3, all of said parts being rigidly Patent No. 478,548, datedJuly 12, 1892. serial No. 423.818. (No more.)

necessary to place ring 7 inside of two of the lugs, place the inwardcurvature inside the other lug, and then turn either ring sufficiently,so that the curvature will pass away from the lug, thus leaving ring 7locked in position by all of the lugs.

In practice I preferably make loop 4 of sheet metal, as shown in thedrawings, and reduce the surface in contact with the inner edge of thetop of the pot by cutting away the top of the loop at the inner edges,as at 9, the object of this special construction being to give good widebearing-surfaces on the inner and outer sides of the pot, and at t-hesame time to remove all superiiuous metal at the portion of the loopwhich comes in contact with the iiange of the lid. This I find, inpractice, to be a valuable feature, as it enables the lid of the coffeeor tea pot to shut down closely, which would be impossible if theholding-loop were left full width at the portion engaging the inner edgeof the pot.

In use the tea or codec is placed in the bag, and the device is thensuspended over the edge of the pot, as clearly shown in Fig. 1, thefilter being preferably placed near the handle, as shown in thedrawings. Loop 4 takes so little room as not to interfere with theclosing of the lid in the slightest, the usual iiange upon the lidpassing inside of it.

Having thus described my invention, I claim- 1. A iilter for the purposedescribed, consistin g of a bag having at its upper end a ring providedwith inwardly-turned lugs, and a holding device consisting of a loopadapted to engage the top of the pot, aloop extending downward withinthe bag to hold it in position in use, and a ring adapted to lit withinthe ring upon the bag and having an inward curvature permitting it topass one of the lugs, the holding device being. locked within the bag byturning one of the rings slightly.

2. A tea or coffee filter consisting of a bag having a ring and lugs atthe top, and a holding device consisting of a ring engaging withinsecured together. In order that ring 7 may the ring in the bag, a loopextending down- IOO ward Within the bag, and a loop adapted to pot, saidsheet-metal loop having a handlo engage the top of the pot. piece 5 andbeing out away at' the top, so as 3.
